Woodpecker CI Configuration Service example
This repository provides a very simplistic example of how to set up an external configuration service for Woodpecker CI The external service gets a HTTP POST request with information about the repo, current build, and the configs that would normally be used. It can then decide to acknowledge the current configs (By returning HTTP 204), or overriding the configurations and returning new ones in the response
Use cases for this system are:
- Centralized configuration for multiple repositories at once
- Preprocessing steps in the pipeline like templating, macros or conversion from different pipeline formats to woodpeckers format
This service is written in go, to run it first copy the config example: cp .env.example .env
Download the public key from your woodpecker instance from http(s)://your-woodpecker-server/api/signature/public-key and save it to file. Set WOODPECKER_CONFIG_SERVICE_PUBLIC_KEY_FILE to the path to that file and add a filtering regex. The repositories that have a name match the filtering regex will receive the config from central-pipeline-config.yaml, while all other repositories will continue using their original configuration.
Then run using go run ..
Make sure to configure your woodpecker instance with the correct endpoint and configure the same secret. See Woodpeckers documentation here
eg:
# Server
# ...
WOODPECKER_CONFIG_SERVICE_ENDPOINT=http://<service>:8000/ciconfig
WOODPECKER_CONFIG_SERVICE_PUBLIC_KEY_FILE=public-key.pem
